Jshell: Execute the snippet by id

/id is used to execute the snippet by ids.

 

Step 1: Open terminal and execute the command jshell.

$jshell
|  Welcome to JShell -- Version 10.0.2
|  For an introduction type: /help intro

jshell>

 

Step 2: Execute below statements.

System.out.println("Hello")

System.out.println("World")

System.out.println("!!!!!")

jshell> System.out.println("Hello")
Hello

jshell> System.out.println("World")
World

jshell> System.out.println("!!!!!")
!!!!!

Step 3: Execute the command /list to see the snippet ids.

jshell> /list

   1 : System.out.println("Hello")
   2 : System.out.println("World")
   3 : System.out.println("!!!!!")

Step 4: Execute the command /2 to execute the statement with snippet id 2.

jshell> /2
System.out.println("World")
World

You can even execute multiple snippets in one statement. For example, /1 3 execute snippets with ids 1 and 3.

jshell> /1 3
System.out.println("Hello")
Hello
System.out.println("!!!!!")
!!!!!

You can even use - to specify start and end snippet ids. For example, /1-3 execute the snippets with ids 1, 2 and 3.

jshell> /1-3
System.out.println("Hello")
Hello
System.out.println("World")
World
System.out.println("!!!!!")
!!!!!
